The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up at Jaconé. This is a consistent, exposed SE spot, so it’s always in the game. The water temp is sitting about average for this time of year.
First up, we’ve got a slow start. Tuesday the 28th and Wednesday the 29th offer small, rideable waves around 2ft to 3ft from the S. The real gem is Wednesday morning with glassy conditions and a light offshore N wind at 5 mph. That’s a beautiful window to get a clean little wave, even if the energy is moderate (173). Afternoon on Wednesday looks alright too with a cross-off breeze and a touch more push at 3ft (280 energy).
Thursday the 30th is a write-off. Onshore and cross-onshore winds kill the quality, with poor surf conditions. Friday the 31st stays mostly poor, with a clean but strong 25 mph cross-off wind in the afternoon – not great for surfing.
Now, Saturday the 1st of August brings a standout. The morning has a gentle 15 mph NE offshore wind with 3ft S swell, and the combined energy jumps to 426 (moderate). It’s clean and there’s enough juice for a fun session. That’s your best bet early on.
Sunday the 2nd and Monday the 3rd are back to small, glassy mornings but with weak, short-period E swell (around 6-7 seconds) – surfable, but nothing special.
The next real highlight lands on Wednesday the 5th of August. Morning glass with a 4ft S swell (11 seconds) and clean conditions. The energy is solid (423). That’s a proper session, with good shape and light winds.
Come Friday the 7th and Saturday the 8th, we see more clean mornings with offshores, swell around 4ft from the ENE, and good energy (327 and 304). Consistent, clean, and fun.
The big one shows up on Sunday the 9th of August. Morning glass with 6ft ENE swell – that’s a solid step up, and the energy is strong (464). This is going to be a punchy, fun wave, but at 6ft, it’s getting a bit much for beginners. The afternoon goes to crap with a 35 mph cross-on, so get on it early.
Looking further out, Tuesday the 11th of August morning looks like a proper standout. A 4ft S swell with a 12-second period, clean offshore NE wind at 15 mph, and very strong energy (716). That’s quality groundswell, clean and powerful. This is the best call in the whole forecast, but it’s a long way out, so keep an eye on it.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
